I was on birth control for 6/7 years with the purpose of regulating my period. Throughout those years I have experienced major anxiety and depression. I recently stopped taking it and noticed an instant change in my mood and daily life. Now I am wondering if it was the cause of my depression. It could have been a culmination of things. What do you think? Have you experienced this?

It's hard to say. BC could have played a part but it is also likely that other situations and circumstances have also made you to become depressed. I think you should talk to a psychiatrist about this.?

As for me, I have only tried emergency BC and it made me super depressed for like almost 2 weeks. But maybe because i was also going through a rough breakup around that time.
